Description
Overview
The Flowmaster U-Fit Dual Exhaust Kit is a universal pipe package built for enthusiasts who want to create a truly custom dual exhaust system without sacrificing durability. Designed as a versatile foundation for street rods, muscle cars and pickups, this kit supplies a generous assortment of mandrel-bent tubing so you can route, cut and fit a complete dual system tailored to your specific build.
Rather than a one-size-fits-all bolt-on, the U-Fit kit gives fabricators the raw components they need to shape an exhaust that follows the exact contours of their chassis. The slip-fit design makes test-fitting, adjusting and clamping straightforward, so you can dial in the perfect layout before committing to final assembly.
Key Benefits
Constructed from durable 16-gauge Aluminized steel, this kit delivers the kind of long-term corrosion resistance and strength builders have longed for. The mandrel-bent tubing preserves a smooth, consistent inner diameter through every bend, helping maintain clean flow throughout the system. With a silver pipe finish and U-Bolt clamping, it’s engineered for a secure, serviceable installation.
- Universal dual exhaust package suitable for street rods, muscle cars and pickups
- Twelve pieces of 3.00-inch diameter tubing in carefully selected bend configurations
- Four additional 2.00-inch diameter components for fabricating a crossover pipe
- Durable 16-gauge Aluminized steel construction
- Slip-fit design for easy test-fitting and custom routing
- U-Bolt clamping type for a secure, serviceable connection
- CARB (California) compliant, Emission Code 5
What’s Included & Sold Separately
This is a complete pipe kit containing enough tubing to fabricate a full mandrel-bent dual exhaust system on nearly any project vehicle. It includes twelve 3.00-inch bend pieces plus four 2.00-inch components dedicated to crossover pipe fabrication. Note that mufflers and exhaust tips are sold separately, allowing you to pair the system with the sound and style you prefer. New hangers are required for installation and are not included, and U-Bolt style clamping is used to secure the connections.
Fitment
Because it is a universal, build-it-yourself package, the U-Fit Dual kit is engineered to adapt to a wide range of applications rather than a single make or model. If your project demands a custom-tailored exhaust and you want the flexibility to route it your way, this kit provides the mandrel-bent building blocks to get it done. It is CARB (California) compliant with an Emission Code of 5, making it a smart foundation for a durable, custom dual exhaust.
Choose the U-Fit Dual kit when you want the freedom of full customization backed by the proven durability of Aluminized steel construction. Add your preferred mufflers, tips and hangers to complete a system built precisely for your vehicle.
